An office building is 188 feet long and 78 feet wide and has six floors, all office space, with 48 receptacles per floor. The distribution system is 120/208-volt, 3-phase, 4-wire. Calculate the lighting feeder volt-ampere (VA) demand load. Answer VA Use 220.43 to calculate the demand for the receptacles. Answer VA Calculate the number of 120-volt, 20-ampere lighting branch circuits for each floor. To determine the minimum number of branch circuits, calculate the answer to the larger whole number. Answer circuits Calculate the number of 120-volt, 20-ampere receptacle branch circuits for each floor. To determine the minimum number of branch circuits, calculate the answer to the larger whole number. Answer circuits
